I keep it clipped to my work lanyard and the 8g weight is barely noticeable until I need to squeeze it. The cube shape fits perfectly in my palm and has saved me from snapping at coworkers during stressful meetings.

I was skeptical about how much good a tiny 8g ball could do, but squeezing it during a long commute genuinely helped me unwind. The compact 4x4x4 cm size clips right onto my bag without adding any bulk.

It fits perfectly on my keychain without adding bulk, and the cube shape gives a nice, firm resistance when I squeeze it. I've been using it during calls and it helps me focus without being distracting.
